Gromov hyperbolicity of Denjoy domains with hyperbolic and quasihyperbolic metrics
Peter Hästö, Henri Linden, Ana Portilla +2
We obtain explicit and simple conditions which in many cases allow one decide, whether or not a Denjoy domain endowed with the Poincare or quasihyperbolic metric is Gromov hyperbol…

Generalized Elliptic Integrals and the Legendre M-function
V. Heikkala, H. Lindén, M. K. Vamanamurthy +1
We study monotonicity and convexity properties of functions arising in the theory of elliptic integrals, and in particular in the case of a Schwarz-Christoffel conformal mapping fr…
